Title:
putting a larger file in synced folder generates large amount of
Watcher events
Status in Syncany:
New
Bug description:
When I copy a somewhat larger file (e.g. a couple of megabytes) into
the synchronized folder then this generates a very large amount of
file watcher events and corresponding indexer updates.

Moving parentKey.reset() from the BufferedWatcher worker thread to the
end of processEvent() to hold of any new events until after processing
seems to solve this (see attached patch).
